What’s the difference between onehalfspacing and line spacing?

Microsoft Word doesn’t do line spacing correctly (unless you multiply the pt value of the text yourself and use the “Exactly” line-spacing option). If you actually measure line height in a graphics-editing program—from the top of the tallest letter to the bottom of a lowest letter— \\onehalfspacing uses exactly 0.5 of this height below each line.

Why does \\ onehalfspacing macro not work properly?

The reason was that the packages had conflict with ” setspace “. On the other hand, without using the ” setspace ” package, the \\onehalfspacing macro didn’t work properly (although it didn’t complain, but the spacing was not as it was supposed to be). This makes the spacing 1.5 times the normal spacing.

It cannot find your ext command. The error lies probably in package iopams and should be noticed there.

The macro ext is undefined.

Where does pdfTeX stop at the end of a command?

Each of the commands above are LaTeX format additions, completely unknown to pdftex and its variants, so pdftex stops at \\documentclass already. Packages always must have the ending .sty, so e.g. hyperref.sty, it’s sufficient to use \sepackage {hyperref} then.

How to avoid undefined control sequence when using latex?

In the bioinfo.cls there is a commented environment also named abstract. This can be an old version of the class and the template provided has not been updated.
